NON-CONDUCTING HAND-WHEEL FOR COCKS, 80C.

SPECIFICATION formingpart of Letters Patent No 413,313, dated October 22, 1889. Application filed May 17, 1889- Serial No. 311,101. (No model.)

- To all whom it may concern.-

Be it known that I, JOHN W. BECKER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Non-Conducting Hand- Wheels for Cocks, Valves, and other Steam: Fittings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to those non-conducting hand-wheels intended to be attached to the stems or spindles of cocks or valves for steam-fittings, to enable the latter to be opened I and closed without burning the hand. These wheels, which are usually made of wood, are apt to be split by the heat and thus rendered useless unless re-enforced by some metal binder; and the object of my invention is to apply such a binder in the construction of the wheels, which is both novel and efficient.

The novelty of my invention will be herewith set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a central sectional elevation of a hand-wheel connected to the upper portion of a valvestem and embodying my invention. Fig. 2 is a corresponding view of the hand-wheel alone with its metal binder. Fig. 3 is a bottom plan view of the hand-wheel.

The same letters of reference are used to indicate identical parts in all the figures.

A represents a hand-wheel of wood or other suitable material usually turned in a lathe, with a periphery rounded in cross-section and with an upper central depression a and a lower concentric depression Z7. (See Fig. 2.) There is a central aperture 0 for the insertion of the shank d of the valve-stem B, which fits tightly therein with a flange-plate e, provided on its upper face with locking-detents e, snugly filling the depression I), with the detents e embedded in the handle.

In the construction of the handle I cut a circular kerf f, Fig. 3, in the depression 6 at its circumference, extending up into the handwheel to about the middle of the point of strain, which in Wheels of ordinary size would be about an eighth of an inch in depth, and

stem, as seen in Fig. 1, is covered and locked in place by the flange e. A washer h is fit ted into the upper depression a, and a ma chine-screw c is insert-ed through said washer and into the tapped end of the shank to look all the parts securely together. The head of the screw, it will be observed, is below the top of the wheel, so that the latter may be firmly grasped by the hand without danger Having thus fully described my invention, I

claim 1. A non-conducting handwheel for valves and steam-fittings, having on its under side a central circular aperture for the reception of the disk or flange-plate of the valve-stem, and having also a circular kerf or groove f above or within said aperture, combined with an independent ring g, inserted in said kerf or groove inside of said aperture, substantially as set forth.

2. The combination, with a valve-stem having a disk or flange-plate 6, provided with the detents or projections e, of a non-conducting hand-wheel having on its under or inner side an aperture 0 for the reception of said disk or flange-plate, and a kerf orgroove fabove or within said aperture, and on its upper-or outer side a recess or central aperture a, the washer 72 in said aperture a, the ring g, inserted in said kerf or groove, and the attaching-screw '6, having its head within the upper or outer face of the hand-wheel.

3. The combination, with a valve-stemhavinga disk or flange-plate c, of anon-conducting hand-wheel having on its under side the aperture for the reception of said disk or flangeplate, and having also a circular groove or kerf f above or within said aperture or disk, and the metal ring 9, independent of or separate from said disk or flange-plate and fitting in said groove or kerf.
